Answer:
$1169.45
Step-by-step explanation:
Using the formula:
where;
Loan amount L = 160000
number of months (n) = 20 × 12 = 240
Lets assume that the interest rate per month c = 6.25% since it is not given.
i.e. (6.25/( 100*12) ) = 5.208 × 10⁻³
∴
P = $1169.45
Answer:
c = 3
Step-by-step explanation:
Using the rule of exponents
=
note that 32 = and 8 = 2³ , then
=
, becomes
=
=
Since the bases on both sides are equal, both 2, then equate the exponents
10c = 3c + 21 ( subtract 3c from both sides )
7c = 21 ( divide both sides by 7 )
c = 3
